Even on that ragweed of the gods, Ambrosia ambrosioides or Canyon Ragweed, you can find loads of galls. According to this site:

"Plants are often found that have numerous pale green warts on the leaf surface. These are caused by nearly microscopic gall mites (Eriophyidae). The mites feed on the plant tissue from the inside of the hollow blisters that are formed by the plant in response to secretions and irritations of the mites. Breaking open the galls will reveal the mites visible with a 20x magnifier."

I learned this one as Desert Rose Mallow; it is in the Mallow Family (Malvacea), but if you call it Coulter('s) Hibiscus, you'll easily remember the scientific name, namely Hibiscus coulteri. Sure is a beauty, whatever you call it.

"Only a few years ago Giant Reed (Arundo donax) posed a serious wildfire hazard to the native trees and plants on Sabino Creek. The 25-ft. stalks burn hot without damaging their roots, which then sprout and re-grow quickly before native vegetation can recover. On Aug. 10, 2009 the Arundo removal project got a big lift from 20 members of the Yuma Wildlands Fire Crew who cut into the Arundo infestation behind Sabino Dam."

"Crew member in the foreground said when he was in grade school his class visited the dam during a field trip by Sabino Canyon Volunteer Naturalists."

Anne says: Let's keep the kids coming back to the canyon, but not the Giant Reed. Keep an eye out for sprouts. It's not over until a lot more birdies sing!

Blue Dicks (Dichelostemma capitatum ssp. pauciflora) is the most commonly used name for this very delicate flower, now in the Asparagus Family. Really. It's the only wildflower in Sabino Canyon in the family that contains all of the agaves. How about that?

A male Western Bluebird. As beautiful as a flower! (Not in the asparagus family.)

This is in the Poppy Family (Papaveraceae), like the Mexican Gold Poppy. It's called Golden Smoke - or Scrambled Eggs (Corydalis aurea) (Don't eat it, though.) We found this one in the sand below the dam. Find the rock with the faucet coming out of it, face it, then walk to the right. Look under the bushes and trees.

This is in the Mustard Family (Brassicaceae), White Bladderpod (Physaria purpurea) and can be seen on Bear Bridge. Look under the trees and bushes that have Wild Cucumber growing on them. (North side, before you get to any water.) There are only a few of these plants, but they are well worth looking for.
A quick reminder to those new to this blog; blue and bold means there's a link - so click on it for more info.

Lots of plants in the Mustard family (Brassicaceae) blooming now. Many are subtle, all are interesting. (Especially to me, as I continue to learn a thing or two about plants.) The top photo shows Tansy Mustard (Descurainia pinnata). Tiny yellow flowers, intricate leaves. The 2nd is my favorite mustard, namely Lace Pod Mustard(Thysanocarpus curvipes). Take a closer look at the seed pods. They are really beautiful.

Many thanks to Ned for continuing to work with me on the point and shoot. (I point, he shoots.)

This vine is growing in the bushes and trees along the north side of the Bear Canyon Bridge and all along the creek-side road. It has several common names: Big Root, Gila Manroot, and Wild Cucumber. Let's go with the latter. (It's always Marah gilensis.) Look at those fruits!

These are both Desert Lupines(Lupinus sparsiflorus) (not the same plant, though). Note the pink/magenta on the flowers in the lower photo. That color indicates the flower has been pollinated. Insects can see they need not bother with that particular flower. Great strategy for producing more seeds; which is what life is all about, when you get right down to it.

Flowers are blooming and that means insects are out and about. This little beauty is a female Sara Orangetip butterfly.

If you like butterflies - and who doesn't? - and want to be able to amaze and impress your family and friends by identifying them, their caterpillars and host plants, head to the visitor center and pick up this new fold-out butterfly field guide by Butterfly Guy Jim Brock. It's even waterproof.

I was hoping this was Green's Lotus (Lotus greenei); but it's more likely Common Lotus (Lotus plebeius) (pg. 101 in Frank Rose's wildflower book). We found this on the rocky 'bank' of the creek behind the dam.

Sunday, February 12, 2012

Red Maids(Calandrinia ciliata) are blooming now! Cross the Bear Canyon Bridge, go left, and look on both sides of the 'road'. (They are blooming elsewhere, of course, but this is where we found them.) These grow low and the pale pink flowers are smaller than a dime.

Saturday, February 11, 2012

This is another one in the Mustard Family (Brassicaceae) that I only learned recently. Jewel Flower or Silverbells (Streptanthus carinatus). A very delicate-looking plant. We found quite a few on the east side of the creek. Cross the Bear Canyon Bridge and take a left. Look right under cacti, shrubs, and trees. (And then make your husband climb in for photos.) Note how the stem seems to push through the leaves.

Friday, February 10, 2012

This beautiful (quarter-sized) blossom is called Ragged Rock Flower(Crossosoma bigelovii). (Even the buds are stunning.) We've seen loads of these plants in the rocky slopes along the road, and there are several plants tucked into the rocks on the Bluff trail (where this photo was taken. Thanks, Ned!)

Like the yellow-orange Fiddleneck, this is another reliable bloomer in the Borage Family (Boraginaceae). It's probably Chryptantha barbigera (Bearded Cryptantha), but the Chryptantha species are hard to tell apart. If you'd like, call these tiny white ones Popcorn Flowers. Look along the road, on the Bluff trail, on the Esperero trail.

Many plants in the Mustard Family (Brassicaceae) are blooming now, including the Lace Pod Mustard(Thysanocarpus curvipes). The white flowers (see link) and the seedpods (pictured above) are VERY tiny, but the seedpods are definitely worth a closer look. If you see a tiny white flower, stop and inspect.

Okay, these photos are from 2010. Ned took photos on the nature walk today that I'll get later. The same plants are blooming, though. Look for them.

This is another primrose, specifically: Mustard Evening Primrose (aka California Sun Cup) Camissonia californica. It's in the Evening Primrose Family (Onagraceae) (and is NOT a mustard). Buds look orange, flower is smaller than a dime on a very slender stem. We saw several on the Bluff Trail this morning. Look carefully, though, as they are often hidden under other plants.

Two plants here: The purple is Desert Lupine(Lupinus sparsiflorus). It's in the Pea Family (Fabaceae) and is only starting to bloom. You'll find this all along the road from the entrance to the Esperero Trail to the entrance to the Bluff Trail and beyond. This year's plants aren't very tall.
The yellow-orange is Fiddleneck(Amsinckia menziesii var. intermedia). Borage Family (Boraginaceae) Also very low growing this year. We saw a number of these on the Bluff Trail.
Stay tuned for tomorrow's "Even More Blooming Now!"

Yes, Carol and I found this at-least-4-inch-stiletto-healed 'shoe' (using the term rather generously) in the canyon. At the risk of being redundant to my very rational readership, I'll make this public service announcement:Under no circumstances should you or anyone you care about wear anything remotely like this.
In the canyon or otherwise. (Mating season or not.)
Cinderella, your shoe is now in its rightful place. You're welcome.

On the Wednesday nature walk, we talked about mosses, algae, and fungi (among other living things). I needed to refresh my memory about algae, so I found this site. It provides a quick overview of the 6 Kingdoms of life. Basically, there are:

Keep in mind: Today, there are 6 Kingdoms. As we learn more about life, the universe, and everything, though, the number of Kingdoms may change (or things may be switched into a different Kingdom or Phylum, etc.). Because DNA sequencing has become relatively inexpensive, it's much easier to see what is related to what and who to whom. Bottom line: All living things share a common ancestor. Very cool!
